T 0 all whom it may concern Be it known that I, ALBERT C. MURPHY, acitizen of the United States, and resident of New York, county of NewYork, and State of New York, have invented an Improvement inDumping-Cars, of which the following is a specification.

My inventionhas for its object the construction of a dumping car whichmay be preferably operated from both ends of the car, whereby the bodymay be rocked upon its bed to dump to eitherside of the car, my presentimprovements providing automatic side doors for the body and guidingmeans for guiding the contents a distance from the road bed when thebody has been tilted into discharging. position.

My object is also' to provide a dumping car of the general characterabove specified in which the automatic mechanism may be thrown'out ofaction, and in which, further, a plurality of the doors upon the sidesof the body may be manually controlled so that only certain doors willopen for discharging the contents of the body whentilted intodischarging position.

My invention consists of constructions in a dumping car which are fullydescribed hereinafter and more particularly defined in the claims, andthese will be better understood by reference to the drawings, in whichFigure 1 is a plan view of a car embodying my improvements; Fig. 9. is aside elevation of one end of the car with portions broken away; Fig. 3is a transverse sectional elevation of my improved car taken on line ofFig. 2:,Fig. 4: is a cross sectional view of one of the latches for thedoors; Fig. 5 is an elevation showing the means for throwing theautomatic mechanism for releasing the doors into or out of action; Fig.6 is a sectional elevat on of one of the adjustable links forcontrollingthe chute plates; Fig. 1 tion on lme g y of Fig. transverse sectionalview is a transverse sec- 5; and Fig. 8 1s a illustrating a modifiedarrangement of the doors.

2 is the longitudinal main frame and has at its respective endsplatforms 2 and 2", in which the means for tilting the body arearranged.

6 represents the dumping body of the. car and is provided with rockers 7on its for dumping to each side ofthe track. The

under part, which rock upon rocker beds 4 arranged transversely of thelongitudinal main frame 2, said construction proyiding for rocking ofthe body to either side of the main frame whereby the car hascapacity 69body is rocked by means. of the racks which are reciprocated verticallyby pinions 32 rotating with longitudinal shafts 31 journaled in bearingsin the brackets 3 forming apart of the main frame 2, ex tending thewhole length of the car and to the platforms at each end. Theselongitudinal shafts 31 are-provided with sproclret wheels 33 below theplatforms and said sprocket wheels are rotated by sprocket chains 31operated by suitable hand power devices 35 arranged within cabs'o'n theplatforms. As shown, one of the shafts 31 may be operated from oneplatform and the. other shaft operated from the other 3 j form, and themanipulation of either s will produce rocking motion to the I, j 6; I donot restrict myself in any manner as to the means employed for rockingthe f vbody, and in respect to the particular means here shown saidmeans is fully set outandf claimed in my application Serial are 848,728,filed July 3, .1914. f v The body 6 may be constructed suitable manner.and suitably braced, but has its sides provided with openingsthroughwhich the contents may be dumped, and these side openings are norm-allyclosed by hinged doors 9 preferably hinged at the upper ends at 10 upona longitudinal girder 8 forming the upper boundary of the body. Thelower portions of these doors are provided with keepers which areengaged by the latches 11, said latches-having capacity for bothautomatic and hand operation. The

automatic feature of these latches is such that when the body is tiltedapproximately. into dumping position the latches release the doors sothat the contentscan only be discharged when the body hasasssumed theproper position for such discharge. 1, ho vever, do not restrictmyselfas to the particu Y also to hold themselves in raised or reie' as-h ingposition upon the shaft 12 when moved into that position by h'andmanipulation.

' Fig. 3

(See dotted line at right hand part of Extending through the rock shaft12 in line with the hub of each of the latches 11 j is a bolt" having ahead 26 at one end and e a" nut 27 at the other. end, and said head andnut'are arranged in slotted portions 28 in the hub of the latch. Byreferring to Fig. 4: it will be seen that the latch 11 may be raised byhand. without disturbing the rock shaft 12 and its bolt, said movementpermitting a release'of the doors 9 when desired without operating therock shaft. Itwill, however, be observed that the rock shaft 12 isrocked in the reverse directionto the hands of a watch; the head 26 andthe nut 27 acting against the wall of the slot 28 will rock the latch toa releasing position. By my improvements this rock shaft'12 is adaptedto j be rocked automatically in the act of tilting the body, or mayremain inactive by hand adjustment in a manner to be later described.Pivoted upon therock shaft 12 are a plurality of arms 13 which may beprovided with a sheet metal plate 14 to constitute a guiding or chuteplate. This chute plate 14 andits arms 13 normally hang substantiallyvertically, but when the body is tilted to the dotted position shown inFig. 3 said chute plate is also tilted into an oblique position asindicated in dotted lines so as to'receive and guide the contents on itsleaving the body,

said chute plate causing the load to be discharged to a distance fromthe side of the track. The means for causing the tilting of the chute.plate 14 and its arms 13 into the oblique position consists of the strut15 and the slotted abutment frame 19 which is secured to' the lower partof the longitudinal main frame and braced by the struts 20. Thestrutsi15' are of the construction illustrated in Fig. (Sand comprise atubular member 16 shifts them andtheir rock shaft support as to makethem assume the inclined position shown in dotted lines in Fig. 3.-While this operation is taking place at the side of the body which islowered, there is another operation upon the chute plates and latches atthe opposite side, namely, that which is rising, but in this case thestrutwill not only have its telescopic members expanded as as a part ofthe chute plate.

shown in dotted lines but the cross pin in will have been drawn upwardto -the highest end of the slot in the slotted guide frame 19, theseadjustments permitting the maintenance of the proper connections betweenthe chute plates and the guides fsothat the strut may properly operatein "the" manner first described when the body is tilted downward in theact of dumping the load.

The shafts 12 for operating the latches 11 and for supporting the chuteplate and frame structures 14 and 13 are respectively jou'rnaled at eachside of the body imme-' diately below the bottom at the outer sideedges. These shafts 12 may be allowed to remain stationary and permitthe latches 11 to be operated by hand as hereinbefore described inreleasing or latching the side doors 9 wholly or .in part, all beinglatched as when the car isto be loaded, and one or more of the doorsunlatched when it is desired to dump only a portion of the load.However, when the latches are to be operated automatically so that allof the doors' are released this result is accomplished more particularlyby" the mechanism shown in Figs. 5 and 7. As the mechanism at each sideof the car is the same in construction it will suffice to describe theconstruction on one side of the car.

Sliding upon the shaft 12 is a sleeve 21, said sleeve being caused torotate or rock with the shaft by reason of the presence of the spline24:. This sleeve 21 is provided with teeth 22 upon its end and it isfurther I provided with the spring 25 which engages notches'2'6, to holdthe sleeve out of or into engagement with the lugs or teeth 23 on one ofthe frames or arms 13 which is rocked The space 23 between the lugs 23is such that the lugs 22 are not "acted upon to lock the shaft 12 untilthe arm 13 and the chute plate carried thereby is raised almost to theinclined position which it must assume when the load is to bedischarged. After this preliminary movement the further movement ofthearm 13 will operate to cause the teeth 23 to engage the teeth 22 androtate the sleeve 21 and the shaft 12 a few degrees, namely,-sufficientto lift the latch 11 to release the doors, whereupon the load pressingagainst the doors forces them open and is automatically discharged overthe inclined chute plates. In the preferred construction I provide thatthe chute plate arm 13 shall move through an angle of 72 degrees duringthe tilting of the body before the latches begin their releasing motionandsthat the latches shall be fully released during a further movement-of approximately 18 degrees,

these movements being'indicated diagram-.- matically in Fig. 7. 5 Uponthe. return movement 1 due to thq'righting of the body the et .1Y llm QjWayfrcm the teeth 224 and may travel approximately through 72 V degreesbefore again operating the shaft 12 in returning itto itsoriginal normalpositlon. In other words, the teeth 23 play between theteeth '22 so thatthey operate upon the-flatter. both in lifting the latches and When; re;sett ing the shaft and latches to their original-ipositions. hen it isdesired that ithe latches shall not be operated automati- 10' callythesleeve '21 is adjusted to the position shown in F g. 5, but when it isrequired that It shall be automatically operated-then the sleeve 21'ismoved to the right so that the teeth 22 will bereceived in the space 23between the teeth 23. When the body is righted' to a horizontal positionand the doors 9 close, the latches 11 are pushed down by "hand to thepositions indicated in Figs. 3. and no engage andhold the doors in,closed position.

llvhiile- I have shown a specific means for puttingsthe rock shafts 12into and out of automahdhperation it is to be understood that-I do'fnotrestrict myself to any particu lar means .for accomplishing thispurpose, for instead of the teeth 23 being operated by the arm 13 of thechute plates 1-.t these teeth may be operated by any other suitablemech-.

anism put into action by thetilting of the body into a dumping position,the construction here shown being by way of example only.

While I prefer that the doors 9 shall be hinged at the top and latchedat the bottom, this is not essential to the invention broadly as will beevident from reference to Fig. 8 In this case the latches 11 are shownat the upper part of the body'whereas the doors 145 are indicated ashinged to the same shaft 12 to which the arms 13 are hinged. In thiscase the doors 11 will actas chute plates for the load and thereforethey may rest directly against the arms 13 and supplement or take theplace of the chute plates 14 shown in Fig. 3. The latches 11 may becarried upon a shaft 12 to which they are connected as indicated in. 4,and this rock shaft 12 may be rocked from the rock shaft 12b connectionsl2 or of iii'nv other suit-able means.

-flVhile I have shown the guides 19 as slotted plates or frames it is tobe understood that I do not restrict myself in this respect as theguiding union between the abutmentstruts 15 and the main frame of thecar may be .made in any suitable manner capable of performing thefunctions or op; erai'ions herein defined.

'While I haye shown my improvements as applied toa dumping car in' thepreferred form. I do not restrictmyself to the details as these may bemodified in any suitable manner without departing from the spirit of theinvention.
